The Slow Mo Guys are just a couple dudes who happen to have a Phantom Flex camera, capable of capturing events at 2,500 frames per second. Dumb jokes aside, their videos are pretty spectacular -- they've amassed an audience of millions on YouTube. In their latest, the guys, aka Gavin Free and Daniel Gruchy, smash a Molotov cocktail against a brick wall and slow down the footage x100. The slow-motion clip is noticeably darker because the camera is only letting in 1/2,500 of a second of daylight per frame. Skip to 1:45 for the fireworks, and don't try this at home.
